Expertises ([TEXT NOT REPRODUCIBLE IN ASCII] 1998) had demonstrated, that as a result of pressure bump of warm damp air in area of cooling towers and the determined removal from them the special microclimate alee is created.

The problem consists that near to a zone of a layout of group of cooling towers at a territory jfchemical (or oil refining) enterprises there are the potential sources of pressure bump in an atmosphere of those or diverse harmful matters, some of which are introduced in Table 5.

Vedeneyev ([MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] 1977) had demonstrated, in particular, that calorific pressure bump of cooling towers at small speeds of a wind can render essential influencing on intensity of eddy diffusion that causes appreciable magnification of ground concentration of an admixture.

0 times exceed magnitude of speed of pressure bump.

However, the account in an aerologic oilpainting of harmful pressure bumps of the chemical enterprises in this work is not planned, as it will demand the big massive of the complementary information.

Depending on the location of cooling towers, their type and power, a lay of land and meteorological conditions pressure bumps of drop moisture in the form of an aerosol from a cooling tower can render the determined negative environmental impact.

Sources of harmful pressure bumps at the enterprises of an oil-and-gas complex usually are torches and chimneys.

Fedoseev known model ([TEXT NOT REPRODUCIBLE IN ASCII] 2006) is offered to allow for a layout of a source of pressure bumps concerning a boundary layer of an atmosphere, a resizing of a boundary layer, allocation of speed of a wind on altitude with variation of a class of stability of an atmosphere and unevenness of a spreading surface.

As a result of interplay of a steam-air plume with pressure bumps of harmful matters of the chemical productions which have been laid out in a zone of propagation of a plume, namely in radius of 2-10 km, under the determined meteorological conditions there is an odds of fallout on soil of the pointed harmful matters.

In Table 5 the structure of pressure bumps of pollutants on the oil-and-gas enterprises of Russia is resulted.
